01 - Preheat oven to 350°F (175°C). Line a standard 12-cup muffin tin with paper liners or lightly grease the cups.
02 - In a large mixing bowl, whisk together the all-purpose flour, granulated sugar, baking powder, baking soda, salt, finely grated fresh ginger, and lemon zest.
03 - In a separate bowl, whisk together the eggs, vegetable oil, plain Greek yogurt, fresh lemon juice, and vanilla extract until fully incorporated and smooth.
04 - Pour the wet mixture into the dry ingredients and stir gently until just combined. Avoid overmixing to ensure tender muffins.
05 - Divide the batter evenly among the muffin cups, filling each about three-quarters full for even rising.
06 - Bake in the preheated oven for 16 to 18 minutes, or until a toothpick inserted in the center emerges clean.
07 - Let muffins cool in the pan for 5 minutes, then transfer them to a wire rack to cool completely.
08 - Combine powdered sugar, lemon juice, and finely grated ginger (if using) in a small bowl. Stir until smooth and pourable.
09 - Drizzle glaze over the cooled muffins. Allow glaze to set before serving.
